Drink to Derive

Anecdotally or statistically, an unhealthy number of mathematicians and math educators around the globe are chain-smokers. Out of habit or addiction, they need to puff out before any proof.

Likewise, it wouldn’t be surprising that a (smaller) percentage of them would also need to drink before they derive any mathematical result, or prove or disprove any conjecture, which is worth gracing the pages of a reputable journal or periodical.

Strong Zero

On a visit to a local supermarket two years ago, I spotted Strong Zero, which led me to tweet about it:

Strong Zero: Something to reward yourself with at the end of a long fruitful day indulging in mathematical proof to destress yourself with fellow boozers.

Then, I had in mind to “derive, then drink,” rather than the other way around. The choice is yours! Know your limits!

If you drink, don’t derive! Really?

So, a little boozing and smoking (in moderation) might debatably be an unspoken (inexpensive?) boost or catalyst to experiencing an aha! When the product of two negatives produces a positive!

A Quickie from Russia

Since we’re on the topic of drinking alcoholic beverages or liquor to boost mathematical productivity, let’s end with a mathematical quickie from Putinland, which was pre-Xed (or tweeted) slightly less than a dozen years ago:

A man and his wife drink a keg of kvas in 10 days. He alone can drink it in 14 days. How long will his wife take to drink a keg?

Challenge: Try solving the above proportion problem in a nontraditional way (with or without a drink)! Better still, use a bar model to do it.

Creatively & productively yours

Calculus for Mature Students

Math Meme from Math Lady Hazel

Like math, calculus needn’t sulk (to any degree)! In the hands of an excited middle-school or high-school math teacher, or with access to some creatively written (or online free) resources, the ABCs of calculus can even be taught to elementary school kids.

Think of Mr. Jaime Escalante who had successfully taught calculus to cohorts of Mexican-American students. There is zero excuse why we can’t emulate him to teaching it to financially disadvantaged or minority groups.

What’s Calculus to You?

Do you parrot the textbook definition of calculus to your students? The mathematics of (instantaneous) change. Or do you share it as the branch of mathematics that measures “how far an object has been going fast,” and “how fast an object has gone far”?

Moons ago, I cheekily approached or indirectly defined calculus via the division of zero as follows:

0 ÷ 0: The Raison d’être of Calculus

With some dose of irreverence, the bête noire of high-school or college math could turn out to be a much beloved topic even among the so-called innumerates or mathematically challenged.

Calculus for the Numerati

It’s debatably said that without an exposure of some delta-epsilon calculus, no man or woman can honestly claim to be “mathematically educated” or “mathematically civilized.” Sounds like mathematical pride or arrogance, isn’t it?

Or just an example of “mathematical elitism” à la Trump for those fakes who declare themselves as being a “very stable genius.” Even Einstein had remarked that calculus was “the greatest advance in thought that a single individual was ever privileged to make.”

Fr: Ryan Truong on Facebook’s “Mathematical Mathematics Memes”

Recently, while working on the Urban Calculus manuscript, I forced myself to reread some of the out-of-print pop calculus titles like David Berlinski’s A Tour of the Calculus, Steven Strogatz’s The Calculus of Friendship, and Mary Stopes-Roe’s Mathematics with Love to get an intuitive feel of the subject again.

For a long time, the thought of taking up the challenge to read Newton’s The Principia (even its annotated version) frightens me, because the complexity of the content is beyond me. I’ve a good excuse not to borrow the thick copy from the university library unless I want to look like a “mathematical snob” carrying it around, or use it as a temporary doorstop.

When Comics and Calculus Converge

Calculus for All

Let’s play our part in sharing the mathematical gospel of Newton and Leibniz that calculus needn’t be a four-letter word—how these two mathematical greats had exorcized the demon out of the division of zero.

Why not strive to be the “James Escalante” of your school, state, or country? You’d be the changemaker or mathematical savior in motivating some undecided or mature students to read a calculus course or module in college?

Differentially and integrally yours
